Direct factory supply from our 180,000㎡ Foshan manufacturing base. Each entrance system below is custom-engineered to withstand Turkey’s distinct microclimates—from the coastal humidity of the Mediterranean and Aegean to the thermal extremes of inland Anatolia.
Thermal Villa Entry
Engineered with multi-chamber T66 aluminum profiles and PA66 nylon thermal break strips. Delivers superior $U$-values down to $1.3 \text{ W/m}^2\text{K}$, blocking winter coastal winds in Istanbul while keeping interiors cool during Izmir summers.
Commercial Fire Exit
Grade 304/316 heavy-gauge stainless steel construction featuring UL 10C panic bars and vertical latching rods. Engineered for maximum emergency exit throughput and fire compartmentalization in commercial complexes, hospitals, and transit hubs across Ankara.
Luxury Grand Villa
A flagship architectural entrance combining solid 3D alloy cast aluminum faceplates with high-tensile steel skeletal armoring and laminated safety glass. Perfect for prestige Bosphorus waterfront Yalı mansions requiring imperial aesthetics and anti-burglary protection.
Oversized Pivot Door
Designed for grand contemporary architectural facades. Features heavy-duty German concealed floor pivot hinges capable of carrying leaf weights up to 500kg. Includes customizable transom lights to flood luxury residential foyers with natural Mediterranean light.
Acoustic Soundproof Pivot
Achieves sound reduction performance up to $R_w = 42\text{dB}$ via high-density acoustic rockwool cores and perimeter magnetic weather seals. Designed for modern urban residences along busy thoroughfares in Istanbul Levent and Maslak districts.
UL 10C Certified Safety
Rigorously tested to North American UL 10C and European EN 16034 fire resistance safety codes. Features intumescent expanding seals that block toxic smoke and heat propagation up to 180 minutes in high-occupancy retail complexes and cinemas.
3-Hour Fire Rated Barrier
Industrial-grade 3-hour fire-rated steel entry systems crafted with galvanized steel frames, mineral wool infill, and heavy-duty panic exit hardware. Essential compliance doors for Turkish industrial zones (OSB), logistics parks, and high-rise commercial emergency stairwells.
3D Carved Solid Wood
Fuses traditional architectural woodworking with modern moisture-proof core technology. Protected by hydrophobic polyurethane lacquers and composite sub-layers, ensuring non-warping performance against Turkey's humid coastal microclimates in Bodrum and Antalya.
A clear specification reference developed by our Foshan engineering R&D team to assist Turkish architectural firms, EPC contractors, and real estate developers in selecting optimal entrance systems.

Turkey bridges continents and microclimates. Our custom doors are engineered with targeted physical characteristics to perform flawlessly across diverse regional requirements.
Coastal properties facing the Marmara, Aegean, or Mediterranean Seas endure continuous salt-laden mist, high atmospheric moisture, and seasonal storms. Standard steel or untreated aluminum doors suffer from pitting corrosion and hardware oxidation within months.
Central and Eastern Anatolia exhibit extreme diurnal and seasonal thermal fluctuations, with summer temperatures reaching +40°C and winter temperatures plunging below -20°C. Inferior entry doors suffer severe frame expansion, seal degradation, and heavy interior thermal bridging.
Financial districts in Istanbul demand heavy-duty entry systems capable of continuous daily usage while fulfilling strict Turkish Municipal Fire Codes (TS EN 16034 and TS EN 14351-1).
High-end resort hotels and historical restoration projects demand entrance doors that harmonize traditional Anatolian motifs with modern security, acoustic damping, and automatic access integration.
As Turkey’s luxury housing and commercial infrastructure markets grow, architectural preferences and building codes are undergoing rapid transformation.
Modern villas in Bodrum, Çeşme, and Kemer are shifting away from traditional double doors toward single oversized pivot doors ($1.8\text{m} \times 3.5\text{m}$+). Architects prioritize clean sightlines, flush floor pivots, and integrated side transoms.
Turkish municipality building inspections mandate strict conformity to TS EN 14351-1 (Windows & Exterior Doorsets) and TS EN 16034 (Fire Resistance). Derki provides full CE test certificates and shop drawings for frictionless site approval.
Luxury residential developments require hidden multi-point electronic locking systems, 3D facial recognition access, and anti-pry steel cores that preserve sleek minimalist aesthetics while providing high-grade residential defense.
Guangdong Derki Doors & Windows Technology Co., Ltd. is a vertically integrated door manufacturer based in Foshan—China's premier architectural aluminum hub. For over 25 years, we have provided direct-from-factory solutions to global project developers.
Source your entire opening package—from grand aluminum main pivot entry doors and cast aluminum gates to interior wooden doors and automatic sectional garage doors—from a single manufacturer, reducing freight, consolidation, and admin overhead.
Our products hold CE, ISO 9001, AS2047 (N6 cyclone rating), and UL 10C fire-rated certifications. Every door shipment includes complete technical submittal packages for smooth Turkish site approvals.
Our engineering team prepares complimentary shop drawings based on your architectural schedules, detailing dimensions, structural sub-framing, threshold clearances, hardware pre-drilling, and glazing specifications prior to production.
Clear answers covering customs clearance, technical submittals, logistics to Turkish ports, and custom hardware integration.
All Derki export doors carry European CE conformity markings, ISO 9001 certification, and detailed factory test reports covering air permeability, water tightness, wind load resistance, and thermal transmittance. We supply complete commercial invoices, packing lists, Certificate of Origin (Form A/CO), and CE declarations to ensure smooth customs clearance through Turkish ports such as Ambarlı (Istanbul), Haydarpaşa, Izmir, and Mersin.
To accommodate building movement during seismic events, our heavy-duty pivot doors and aluminum entrance frames utilize high-tensile T66 aluminum structural tubes and heavy steel anchors. Frame corner joints are double-crimped and corner-injected with structural epoxy, allowing the door assembly to withstand lateral shear stress without glass breakage or frame racking.
Doors are packed with protective surface film, dense corner guards, moisture-resistant wrapping, and heavy export plywood crates with internal steel banding. Typical ocean freight transit time from Nansha/Yantian (Guangzhou/Shenzhen) to Istanbul (Ambarlı/Kumport) or Mersin is approximately 22 to 28 days. We support FOB, CIF, and DDP shipping terms.
Yes. Every entrance system is custom-manufactured. We can match any RAL color, metallic finish, wood-grain heat transfer, or anodized texture. Furthermore, our frames can be pre-machined for your preferred hardware, including Italian Motura/Cisa locks, German Dormakaba/Geze pivot hinges, or localized smart access controllers.
After receiving your door schedule or elevation drawings, our engineering team generates 2D CAD shop drawings within 48 hours. Production begins only after your architect or project manager approves structural dimensions, swing direction, threshold details, and glass specifications.
For high-humidity and high-salinity coastal locations, we recommend our PVDF-coated aluminum alloy entrance systems or 3D cast aluminum doors. PVDF fluorocarbon coatings provide exceptional UV and salt spray protection, preventing color fading, chalking, and oxidation.
Send us your project specifications, door schedules, or CAD drawings. Our engineering team will provide custom technical recommendations, price quotes, and CAD shop drawings within 24 to 48 hours.
